RELATED APPLICATION

This application is a continuation-in-part of U.S. provisional application 61/692,641, re “AV-HALT Compounds for treatment of Viral Infections,” filed 23 Aug. 2012.

BACKGROUND OF INVENTION

Human immunodeficiency virus (HIV) infection (which results in Acquired Immune Deficiency Syndrome, AIDS) is a relatively new infection in the human population, but it has quickly risen to one of the foremost health problems in the world. HIV/AIDS has now become the leading cause of death in sub-Saharan Africa, as well as the fourth biggest killer worldwide (BMJ 2001; 323(7324):1271). At the end of 2010, it was estimated that more than 34 million people were living with HIV infection worldwide, including around 16.8 million women and 3.4 million children (World Health Organisation data). In 2010, there were 2.7 million people newly infected with HIV, and the death toll due to AIDS reached 1.5 million people.

Low- and middle-income countries are the most plagued by HIV (about 97% of new infections are registered there), but adult and child deaths due to AIDS in 2010 were 30,000 in western industrialised countries.

Better treatment methods are now known to prolong the life of patients with HIV infection, but no cure has been found yet for this disease.

Current anti-HIV drugs target several different stages of the HIV life cycle, and several of the enzymes that HIV requires to replicate and survive (Arts et al. Cold Spring harb Perspect Med 2012:2(4):a007161). Some of the commonly used anti-HIV drugs include nucleoside/nucleotide reverse transcriptase inhibitors, NRTIs (such as emtricitabine, stavudine, ddI, ddC, d4T, 3TC, zidovudine, abacavir, tenofovir etc); non-nucleoside reverse transcriptase inhibitors, NNRTIs (such as rilpivirine, etravirine, nevirapine, efavirenz and delavirdine); protease inhibitors, PIs (such as saquinavir, ritonavir, indinavir, nelfinavir, amprenavir, lopinavir and atazanavir); entry inhibitors, including fusion inhibitors (such as enfuvirtide, maraviroc, ibalizumab etc) and others, such as the integrase inhibitor isentress (raltegravir) (http://www.fda.gov/ForConsumers/byAudience/ForPatientAdvocates/HIVandAIDSActivities/ucm118915.htm).

The condition where T cells engage in uncontrolled cell division is called T cell hyperproliferation, leading to immune hyperactivation. T cells are immune system cells that can develop the capacity to kill infected or neoplastic cells. When T cells are contacted by antigens they become activated, or sensitised, and proliferate, that is, appear in greater numbers (Grossman et al. Nat Med 2006; 12; 289-295, Brenchley et al. Nat Med 2006; 12:1365-1371). This is a normal physiological process, which is useful to protect the host from “sick cells” (tumor cells and infected cells).

However, excessive T cell activation, and particularly prolonged, excessive activation can contribute to disease progression and is considered a key pathogenetic factor in several chronic diseases such as cancer and chronic infectious diseases including HIV/AIDS (Sodora et al. AIDS 2008 22:439-446, Hellerstein et al. J Clin Invest 2003; 112:956-966, Liovat et al. PLOS ONE 2012; 7(10):e46143, Cossarizza et al. PLOS ONE 2012:7(12):e50728, Hunt et al. AIDS 2011; 25(17):2123-2131).

In addition, HIV infection of T cells depends on active division and proliferation of such cells. Firstly, infected dividing T cells produce a large amount of HIV particles (approximately 8-10 fold more than in quiescent T cells). Secondly, antigenic stimulation by such HIV particles sustains further T cell activation or proliferation, as mentioned before. This results in a dangerous “vicious cycle”. In addition to direct antigenic stimulation by HIV, microbial translocation across impaired gut-associated lymphoid tissues (GALT) throughout the course of HIV disease also sustains elevated T cell activation/proliferation (Brenchley et al. Nat Med, 2006. 12(12): p. 1365-71). This chronic cycle of events, over time, exhausts the immune system. Therefore, limiting T cell hyperactivation and hyperproliferation will have a dual effect: it will not only suppress HIV replication, but it will also prevent the loss of functional CD4 T helper cells and slow down disease progression.

In order to try to address this unmet medical need we have tried to develop compounds designed to provide both an antiviral and an antiproliferative component.

In order to establish the proof of concept for this approach in humans, we combined into a single capsule, two readily available generic drugs, hydroxyurea (HU) and didanosine (ddI), which we called VS411. In VS411, ddI is the antiviral component and HU is the antiproliferative component. The NRTI, ddI has been used extensively in the treatment of HIV in combination cocktails as a direct acting antiretroviral agent targeting the HIV encoded reverse transcriptase enzyme activity. HU is an antiproliferative agent indicated for the treatment of different neoplastic as well as non-neoplastic diseases such as sickle cell anemia and psoriasis. HU has been used for the treatment of HIV-infected individuals, especially in combination with antiretroviral drugs, such as ddI. HU inhibits the cellular enzyme ribonucleotide reductase, blocking the transformation of ribonucleotides into deoxyribonucleotides, thus depleting the intracellular deoxynucleotide triphosphate (dNTP) pool, and arresting the cell cycle in the G1/S phase (Lori AIDS, 1999; 13(12):1433-42). By depleting the dNTP pool, HU also strongly inhibits viral deoxyribonucleic acid (DNA) synthesis through the virally encoded reverse transcriptase. Moreover, HU can also suppress virus replication by slowing down the rate of T-cell proliferation (as stated above, HIV-1 needs actively dividing cells to optimally replicate).

VS411, was first studied in a Phase I clinical trial in which it exhibited a favourable safety profile and the best formulation was identified (De Formi et al. Br J Pharmacol 2010; 161(4):830-843). VS411 was then investigated in a Proof-of-Concept multinational Phase II trial. In the course of this Phase II study, VS411 exhibited excellent safety and tolerability profiles and reduction in viral load and immune activation after just 28 days of therapy. These results provided solid Proof-of-Concept evidence that therapeutics with antiviral and antiproliferative activities can provide a clinically significant benefit in the treatment of HIV/AIDS (Lori et al. PloS ONE 2012; 7(10): e47485. doi:10.1371/journal.pone.0047485).

Recently, attention has also been turned to cyclin-dependent kinases (CDKs), key regulators of the cell cycle and RNA polymerase II transcription. Cyclin-dependent kinases (CDKs) are non-receptor serine-threonine protein kinases that require cyclin for their activity and play a fundamental role in controlling cell cycle progression. Cell division is a highly regulated process responding to cellular signals both within the cell and from external sources (Gerard et al. Front Physiol 2012; 3:413).

To date, thirteen CDKs have been identified in humans (Chen et al. Biochem Biophys Res Commun. 2007, 354, 735-40; Mani et al. Exp. Opin. Invest. Drugs 2000; 9(8):1849-1870, Sergere et al. Biochem. Biophys. Res. Commun. 2000, 276, 271-277, Hu et al. J. Biochem. Chem. 2003; 278(1 0):8623-8629).

Because CDKs play an important role in the regulation of cellular proliferation, CDK inhibitors could be useful in the treatment of cell proliferative disorders such as cancer, neuro-fibromatosis, psoriasis, fungal infections, endotoxic shock, transplantation rejection, vascular smooth cell proliferation associated with artherosclerosis, pulmonary fibrosis, arthritis, glomerulonephritis and post-surgical stenosis and restenosis (U.S. Pat. No. 6,114,365).

CDKs are also known to play a role in apoptosis. Therefore CDK inhibitors could be useful in the treatment of cancer; autoimmune diseases, for example systemic lupus, erythematosus, autoimmune mediated glomerulonephritis, rheumatoid arthritis, psoriasis, inflammatory bowel disease, and autoimmune diabetes (Roberts et al. J Natl Cancer 2012; 104(6):476-487, Zoja Arthritis Rheum 2007; 56:1629-1637). Indeed several pharmacological CDK inhibitors (PC's) are currently in clinical trials as potential cancer therapeutics (Benson et al. Br J Cancer 2007; 96(1):29-37, Luke et al. Clin Cancer 2012; 18(9):2638-2647).

During the last few years, the antiviral effect of PCIs has also been observed against a number of viruses, including HIV. It has been described that HIV-1 replication could be affected by inhibiting CDKs (de la Fuente, et al. Current HIV Research, 2003, 1(2), 131-152; Y. K. Kim et al. Molecular and Cellular Biology, 2002; 22(13):4622-4637). In particular, CDK9 has been reported as being essential for HIV-1 replication. CDK9 forms together with cyclin T1 the human positive transcription elongation factor (PTEFb) regulating elongation phase of RNA polymerase II (RNA Pol II) dependent transcription (Price et al. Mol Cell Biol 2000, 20:2629-2634; Peterlin et al. Mol Cell 2006; 23:297-305). P-TEFb specifically activates transcription from the HIV-1 long-terminal repeat (LTR) promoter (Bieniasz et al. PNAS 1999; 96:7791-7796). After transcription initiation at the LTR, the newly transcribed transactivation responsive (TAR) RNA hairpin recruits the HIV-1 Tat protein, which binds to the cyclin T1 subunit of P-TEFb and recruits the kinase complex to phosphorylate Pol II (Bieniasz et al. PNAS 1999; 96:7791-7796, Zhang et al. J Biol Chem 2000; 275:34314-34319). HIV-1 Tat has recently been suggested to manipulate P-TEFb functional equilibrium by recruiting it from the large inactive complex thus increasing the active pool for efficient HIV-1 transcription (Barboric et al. Nucl Acids Res 2007; 35:2003-2012, Sedore Nucl Acids Res 2007; 35:4347-4358). The P-TEFb kinase activity is both essential and limiting for viral replication, and inhibition of P-TEFb by small molecules such as DRB 1 abrogates both viral transcription and replication (Flores et al. Proc. Natl. Acad. Sci. USA. 1999, 96(13):7208-13). The most potent P-TEFb inhibitor flavopiridol 2 effectively blocks HIV-1 Tat-transactivation and viral replication by inhibiting P-TEFb kinase activity at non-cytotoxic concentrations without affecting cellular transcription (Chao J Biol Chem 2000; 275:28345-28348, Chao J Biol Chem 2001; 276:31793-31799). RNAi-mediated gene silencing of PTEFb inhibits Tat-transactivation and HIV-1 replication in host cells with no effects on cell viability (Chiu J Virol 2004; 78:2517-2529). Furthermore, direct inhibition of CDK9 using a dominant negative form has been shown to potently inhibit HIV-1 replication without affecting RNA Pol II transcription and cell viability (Flores et al. Proc. Natl. Acad. Sci. USA. 1999, 96(13):7208-13, Salerno et al. Gene 2007; 405:65-78).

When pathogens infect a host, they must manipulate its signal-transduction pathways (the intracellular circuits that transmit extracellular signals from the cell surface to the nucleus and back) required for cellular function and survival (Coley et al. Exp Opin Biol Ther 2009). Preventing pathogens from hijacking such pathways via compounds exerting their action against certain cellular kinases that play key roles in cell signaling, generates a firewall against infection. The benefit of such an approach is that the target for the therapeutic intervention is directed primarily on the host-cell kinases, rather than on pathogen encoded targets. An important consequence of such an approach is that it minimizes the problem of drug resistance. Treatment with typical anti-infective drugs, which act directly on a pathogen encoded target, can be rendered ineffective due to generation of drug resistant variants (Thompson et al. JAMA 2012; 304(3):321-333, UK Coll Group J Inf Dis 2005). These drug resistant variants can occur rapidly, due to spontaneous mutations to the pathogen encoded target and poor proofreading mechanisms during the very short replication cycle of the pathogen. Mammalian host cellular enzymes are much less prone to mutations than microbial ones due to the fact that the mammalian host cell has a much more efficient proofreading mechanism and substantially longer replication cycle. Moreover, since targeting a host-cell kinase would be distal to a pathogen-encoded target this approach should therefore diminish the chances for developing pathogen resistance to such a drug.

Based on this rationale, we embarked on an initial screen for anti-HIV compounds chosen among a library of CDK9 inhibitors, PCT international application (published 30 Jun. 2011 as WO2011077171) “4-Phenylamino-Pyrimidine Derivatives having Protein Kinase Inhibitor Activity” (“PKI”) by Greff et al.

Unexpectedly, the results of the activity tests on such a library (which produced a number of initial hits) highlighted the lack of a direct correlation between CDK9 activity and the anticipated anti-HIV activity. In most cases there was no correlation whatsoever between CDK9 inhibition and anti-HIV activity, as compounds with potent CDK9-related IC₅₀ exhibited poor anti-HIV profiles and vice versa.

This prompted us to explore a new approach: modifications on the original library compounds were proposed, synthetic routes were designed and reduced to practice by synthesizing the novel compounds, the compounds were then tested one by one, resulting in a novel class of molecules with the required properties, that are the subject of the present invention. As the CDK9 inhibitory activity and selectivity of these molecules is not predictive of the antiviral and/or antiproliferative activity they act by an as yet unknown mechanism.

FIELD OF THE INVENTION

The invention therefore encompasses the discovery of novel drugs whose discovery required the experimental testing for their antiviral activity, as their anti-HIV properties could not be deduced a priori just by examination of their CDK9 activity. In addition, to their stand-alone antiviral activity, these novel compounds preferably exhibit the additional attractive antiproliferative activity, thus providing a means for anti-HIV and antiproliferative activity with a single molecule.

Based on their properties, the compounds described in this current invention have the potential to be applied to a variety of additional antiviral indications and chronic conditions. Inflammation, immune hyperactivation and immune cell hyperproliferation are, in fact, hallmarks of many chronic infections, as well as the cardiovascular, inflammatory and metabolic disorders, tumors, and aging that result from chronic, uncontrolled inflammation.

DESCRIPTION OF RELATED ART

In the context of the current invention, the following references present the general state of the art:

Most of the known CDK inhibitors, such as Roscovitine, Olomoucine, purvalanols, paullones, indolinones and 7-hydroxy-staurosporine, rely on the inhibition of CDK1 and CDK2 for antitumor activity (Current Opinion in Pharmacology, 2003, 3, 1-9). A summary of known CDK inhibitors is given by M. Huwe et al. (A. Huwe et al. Angew. Chem. Int. Ed. Engl. 2003; 42(19):2122-38).

WO2011077171 A1 discloses certain 4-phenylamino-pyrimidine derivatives having protein kinase inhibitor activity. In particular, the invention described in WO2011077171 A1 relating to novel 4,6-disubstituted aminopyrimidine compounds, has a main element of novelty based on arylaminopyrimidines that have a substituted aryl part containing —(CH₂)_(n)—W substituents (with n being preferably 1 to 3). Preferred meanings for W include methanesulfonamide, thiophene, indolyl or isoindolyl, phthalimido or benzoimidazo-1-yl groups.

The compounds in the patent represent a library of compounds linking their CDK9-inhibition activity with protein kinase-related diseases such as infectious diseases and cell proliferative diseases. Their structure is different from the compounds we claim in this patent, because the compounds in patent WO2011077171 A1 are only mono substituted pyrimidin-4-ylaminophenyl derivatives.

Bioorganic & Medicinal Chemistry Letters 19 (2009) 17-20 (Steele et al.) reports small molecule β-secretase inhibitors with structural analogies to the compounds herein described. Despite the degree of structural analogy to compounds herein claimed, it is worth noting that the compounds presented in the Steele paper show two main differences:

1) they are presented as Alzheimer's disease (AD) inhibitors acting on β-secretase BACE1 (belonging to the aspartyl protease class of catabolic enzymes); 2) des-dimethylamine compounds described have structure

and specifically lack any substituent on the aryl ring positioned in the 6-position of the pyrimidine ring. Moreover, substituents X have been chosen among Me, H, Cl, Br, F, OMe, Ph and allyl, while Y substituents listed are HO₂, NH₂, NHAc and N-Methyl mesilamide.

In a further refinement of the SAR for the 6-position of the pyrimidine, the authors study Z substituents where Z is Ph, 2′(N,N dimethyl)benzene, 4′(N,N dimethyl)benzene, 2′-methylbenzene, 4′-biphenyl,

but no Z substituents with —OR have been reported in the paper.

US 2009/0099183 A1 discloses lysophosphatidic acid acyltransferase inhibitors based on pyrimidines with structural analogies to the compounds herein described. The structures originally covered in the initial application were generally of the formula:

where R¹-R⁷ are hydrogen or non-hydrogen substituents, Q is a heteroatom or heteroatom attached to one or more methylene groups, and two of X, Y and Z are N with the third being CH or a substituted C. The requirement that two of X, Y and Z are N is consistent with the compounds including a pyrimidine ring.

Preferred embodiments include the following selections for the general formula above. Such preferred embodiments include where X, Y and Z are N, CH or CR. R of CR is alkyl, alkoxy, halo (preferably Cl or Br), NH₂, NHR′ or NR′R″ where R′ and R″ independently are alkyl. Particularly preferred is where X and Y are N.

Preferred embodiments include where Q is a heteroatom (preferably N, O or S) and may be attached to one or more methylene groups to provide additional spacing between the pyrimidine ring and the phenyl ring possessing R⁴, R⁵ and/or R⁶. Q may be NR where R is H or alkyl. Where there are one or more methylene groups, the heteroatom may be oriented such that it is attached directly to the pyrimidine ring or attached directly to the phenyl ring possessing R⁴, R⁵ and/or R⁶. For example, Q may be RN—(CH₂)_(n), (CH₂)_(n)NR, O—(CH₂)_(n), (CH₂)_(n)—O, S—(CH₂)_(n) or (CH₂)_(n)—S, where n is typically 1-10 and R is H or alkyl. Particularly preferred is where Q is NH.

The inventors had to elect one species as the lead, which is quite different from the compounds claimed in the present patent. The elected species represents the same formula described above wherein: X and Y are N, Z is CH; Q is NH; R¹ is Phenyl-CH₂—O—; R² is Br; R³ is NH₂; R⁴ is N⁺(═O)O⁻; and R⁵, R⁶ and R⁷ are H.

Current Medicinal Chemistry 2011; 18(3): 342-358 (Németh et al.) reports a selective family of CDK9 inhibitors based on the 4-phenylamino-6-phenylpyrimidine nucleus that could have potential as anti-HIV compounds. The starting point for the synthesis of these selective CDK9 inhibitors and their evaluation in the treatment of HIV infection was derived from two other publications:

-   a) Choidas, A.; Backes, A.; Cotten, M.; Engkvist, O.; Felber, B.;     Freisleben, A.; Gold, K.; Greff, Z.; Habenberger, P.; Hafenbradl,     D.; Hartung, C.; Herget, T.; Hoppe, E.; Klebl, B.; Missio, A.; Mu     ller, G.; Schwab, W.; Zech, B.; Bravo, J.; Harris, J.; Le, J.;     Macritchie, J. Pharmaceutically active 4,6-disubstituted     aminopyrimidine derivatives as modulators of protein kinases. PCT     Int. Appl. WO 2005026129, 2005; Chem. Abstr., 2005, 142, 336376; -   b) Wabnitz, P.; Schanerte, H.; Stumm, G.; Freitag, J.     Pyrimidine-based CDK inhibitors for treating pain. PCT Int. Appl. WO     2006/125616, 2006; Chem. Abstr. 2007, 146, 781.

The described compounds are synthesised starting from 4-chloro-6-(substituted-phenyl)-pyrimidines and fall into different categories, described by the general structure:

B is described as H or Me. In the cases of B═H, depending on C(H, Me, Cl, F, NO₂, NH₂), the compounds reported in the paper can be either monosubstituted or disubstituted. The key aspect of the paper is that the compounds described are derived making modifications on the (6-phenyl-pyrimidin-4-yl)-phenylamine core structure in order to yield selective CDK9/CycT1 kinase inhibitors, with the assumption that selectivity in CDK9 inhibition is a major aspect for the potential to inhibit HIV-1 propagation. However, the experimental data set that is presented in this paper is certainly not conclusive for the activity of the compounds in HIV. As a matter fact when the present inventors tested the activity of the most promising CDK9 inhibitors it became clear that there is no direct correlation between CDK9 activity and viral inhibition.

BRIEF SUMMARY OF THE INVENTION

As discussed before, several aminopyrimidine derivatives have been disclosed in the literature, and some of them have been described as potential compounds with applications in the HIV field. However, none of the compounds exemplified therein has been encompassed in the general formula (I) of the present application, nor is the evidence of anti-HIV activity very convincing.

In fact during their research the present inventors surprisingly found that only few compounds with good CDK9 activity exhibited potent anti-HIV activity. This inconsistency suggests that these compounds target a cellular mechanism that is as yet not identified.

The present inventors have now discovered that compounds of formula (I), described below, exert a potent stand alone anti-HIV activity which in the preferred cases is also combined with a potentially attractive antiproliferative activity in the same molecule, irrespective of whether they exhibit a good or bad CDK9 inhibitor activity. Thus, these compounds provide for a potentially new method to treat HIV disease.

Compounds claimed in paper Current Medicinal Chemistry 2011; 18(3):342-358 (Németh et al.), which would fall in the claims of the present application, are excluded from the present general formula.

Accordingly, a first object of the present invention is to provide novel 4,6-disubstituted aminopyrimidine compounds represented by formula (I), which possess aromatic substituents, which are directly or indirectly attached to two non-adjacent carbons of the pyrimidine ring. The general formula of the compounds is the following:

DETAILED DESCRIPTION OF THE INVENTION

Prior to setting forth the invention, it may be helpful to an understanding thereof to set forth definitions of certain terms to be used hereinafter.

In the present description, the term “alkyl” refers to a monovalent straight or branched chain, saturated aliphatic hydrocarbon radical having a number of carbon atoms in the specified range. Thus, for example, “C₁₋₆ alkyl” (or “C₁-C₆ alkyl”) refers to any of the hexyl alkyl and pentyl alkyl isomers as well as n-, iso-, sec- and t-butyl, n- and iso-propyl, ethyl and methyl. As another example, “C₁₋₄ alkyl” refers to n-, iso-, sec- and t-butyl, n- and isopropyl, ethyl and methyl.

The alkyl group may be substituted or unsubstituted. When substituted, the substituted group(s) is preferably one or more independently selected from alkyl, cycloalkyl, heteroalicyclic, aryl, heteroaryl, haloalkyl, halo, hydroxy, alkoxy, mercapto, cyano, sulfonamidyl, aminosulfonyl, acyl, acyloxy, substituted imino and substituted amino.

The term “cycloalkyl” refers to any monocyclic or bicyclic ring of an alkane with a number of carbon atoms in the specified range. For example, “C₃₋₈ cycloalkyl” (or “C₃-C₈ cycloalkyl”) is therefore referred to cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl.

“Azacycloalkyl” is referred to a cycloalkyl group as defined above, in which one replacement of the ring carbons with a nitrogen occurs.

The term “heterocycloalkyl” refers to a cycloalkyl group as defined above in which one of the ring carbons has been replaced with a heteroatom chosen among N, O, S.

“Alkenyl” includes monovalent hydrocarbon radicals having straight, cyclic, or branched moieties, and combinations thereof, which comprise at least one carbon-carbon double bond. The alkenyl group may be substituted or unsubstituted.

When substituted, the substituted group(s) is preferably one or more independently selected from alkyl, acyl, cycloalkyl, heteroalicyclic, aryl, haloalkyl, alkoxy and substituted amino.

“Alkoxy” refers to the group “−O-alkyl” which includes, by way of example, methoxy, ethoxy, n-propoxy, i-propoxy, n-butoxy, t-butoxy and the like. It further refers to the group “—O-alkyl-W-alkyl” where W is O or N; for example, —O—(CH₂)_(n)—W—(CH₂)_(m) where n and m are independently 1-10. The alkoxy group may be unsubstituted or substituted, for example with an alkyl, cycloalkyl, alkenyl, acyl, aryl or heterocycle group(s).

“Substituted amino” denotes the group —NRR, wherein each R group is independently selected from hydrogen, hydroxy, acyl, alkyl, cycloalkyl, aryl, or the R groups can be joined together with the nitrogen to form a heterocyclic ring (e.g., piperidine, piperazine, or a morpholine ring).

“Substituted imino” denotes the group ═NR, wherein R is preferably selected from hydrogen, hydroxy, alkyl and acyl.

“Aryl” refers to an unsaturated aromatic carbocyclic group of 6 to 14 carbon atoms having a single ring (e.g., phenyl) or multiple condensed rings (e.g., naphthyl or anthryl). The aryl group may be unsubstituted or substituted; in the latter case, the substituent or substituents preferably are selected independently from alkyl, aryl, haloalkyl, halo, hydroxy, alkoxy, mercapto, cyano, sulfonamidyl, aminosulfonyl, acyl, acyloxy, nitro, and substituted amino.

“Heterocycle” includes “heteroaryl” and “heteroalicyclic”.

Examples of heterocycles include oxazole, piperidine, piperazine and morpholine.

The term “heteroaryl” is referred to (i) a 5- or 6-membered heteroaromatic ring containing from 1 to 4 heteroatoms independently selected from N, O and S, wherein each N is optionally in the form of an oxide, or (ii) a 9- or 10-membered bicyclic, fused ring system which contains from 1 to 4 heteroatoms independently selected from N, O and S, and wherein in the fused ring system any one or more of the rings contain one or more of the heteroatoms, at least one ring is aromatic, each N in a ring is optionally in the form of an oxide, and each S is optionally S(O) or S(O)₂. Suitable heteroaryls include, for example, pyridinyl, pyrrolyl, pyrazinyl, pyrimidinyl, pyridazinyl, triazinyl, thienyl, furanyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isooxazolyl, oxadiazolyl, quinolinyl, tetrahydroquinolinyl, isoquinolinyl, tetrahydroisoquinolinyl, indolyl, isoindolyl, benzodioxolyl, benzopiperidinyl, benzisoxazolyl, benzoxazolyl, chromenyl, chromanyl, isochromanyl, cinnolinyl, quinazolinyl, benzothienyl, benzofuranyl, imidazo[1,2-a]pyridinyl, benzotriazolyl, dihydroindolyl, dihydroisoindolyl, indazolyl, indolinyl, isoindolinyl, quinoxalinyl, quinazolinyl, 2,3-dihydrobenzofuranyl, 2,3-dihydrobenzo-1,4-dioxinyl

benzo-1,3-dioxolyl

thiazolyl, and isothiazolyl.

“Cycloalkyl” encompasses cyclic alkyl groups that contain between 3 and 8 carbon atoms and have a single cyclic ring, illustrated by cyclopropyl, cyclobutyl, cyclopentyl, and cyclooctyl. The cycloalkyl ring may be substituted or unsubstituted.

Again, a substituted cycloalkyl ring carries one or more substituent groups, independently selected preferably from alkyl, aryl, haloalkyl, halo, hydroxy, alkoxy, mercapto, cyano, sulfonamidyl, aminosulfonyl, acyl, acyloxy, vitro, and substituted amino.

“Heteroalicyclic” refers to monocyclic or fused ring groups having in the ring(s) one or more atoms, preferably selected from nitrogen, oxygen and sulfur. The rings may also have one or more double bonds. However, the rings do not possess a completely conjugatedπ-electron system. The heteroalicyclic ring may be either substituted or unsubstituted.

When substituted, the substituted group(s) preferably are selected independently from alkyl, aryl, haloalkyl, halo, hydroxy, alkoxy, mercapto, cyano, sulfonamidyl, aminosulfonyl, acyl, acyloxy, nitro, and substituted or unsubstituted amino.

The term “saturated or mono-unsaturated heterocyclic ring” refers to (i) a 4- to 7-membered, saturated or mono-unsaturated heterocyclic ring containing at least one carbon atom and from 1 to 4 heteroatoms independently selected from N, O and S, where each S is optionally oxidized to S(O) or S(O)₂ or (ii) a 6- to 10-membered saturated or mono-unsaturated, bridged or fused heterobicyclic ring containing from 1 to 4 heteroatoms independently selected from N, O and S, where each S is optionally oxidized to S(O) or S(O)₂. Suitable saturated heterocycles include, for example, azetidinyl, pyrrolidinyl, imidazolinyl, tetrahydrofuranyl, pyrazolidinyl, piperidinyl, piperazinyl, hexahydropyrimidinyl, morpholinyl, thiomorpholinyl, thiazolidinyl, isothiazolidinyl, oxazolidinyl, isoxazolidinyl, thiazinanyl azepanyl and diazepanyl. A class of suitable saturated or mono-unsaturated heterocyclic rings is represented by 4- to 7-membered rings containing at least one carbon atom and from 1 to 4 heteroatoms independently selected from N, O and S, where each S is optionally oxidized to S(O) or S(O)₂. Another suitable class consists of 5- or 6-membered saturated heterocyclic rings containing a total of from 1 to 2 heteroatoms selected from 1 to 2 N atoms, zero to 10 atom, and zero to 1 S atom, wherein the S atom is optionally S(O) or SO₂. Suitable mono-unsaturated heterocyclic rings include those corresponding to the saturated heterocyclic rings listed in the preceding sentence in which replacement of a single bond with a double bond occurs (e.g., a carbon-carbon single bond is replaced with a carbon-carbon double bond).

It is understood that the specific rings and ring systems suitable for use in the present invention are not limited to those listed in the preceding paragraphs. These rings and ring systems are merely representative.

Unless it is expressly stated to the contrary or is otherwise clear from the context, any of the various cyclic rings and ring systems described herein may be attached to the rest of the compound at any ring atom (i.e., any carbon atom or any heteroatom) provided that a stable compound results.

Unless expressly stated to the contrary, all ranges cited herein are inclusive.

For example, a heteroaromatic ring described as containing from “1 to 4 heteroatoms” means the ring can contain 1, 2, 3 or 4 heteroatoms. It is also to be understood that any range cited herein includes within its scope all of the sub-ranges within that range. Thus, for example, a heterocyclic ring described as containing from “1 to 4 heteroatoms” is intended to include as aspects thereof, heterocyclic rings containing 2 to 4 heteroatoms, 3 or 4 heteroatoms, 1 to 3 heteroatoms, 2 or 3 heteroatoms, 1 or 2 heteroatoms, 1 heteroatom, 2 heteroatoms, 3 heteroatoms, and 4 heteroatoms. As another example, a phenyl or naphthyl described as optionally substituted with “from 1 to 5 substituents” is intended to include as aspects thereof, a phenyl or naphthyl substituted with 1 to 5 substituents, 2 to 5 substituents, 3 to 5 substituents, 4 to 5 substituents, 5 substituents, 1 to 4 substituents, 2 to 4 substituents, 3 to 4 substituents, 4 substituents, 1 to 3 substituents, 2 to 3 substituents, 3 substituents, 1 to 2 substituents, 2 substituents, and 1 substituent. When any variable occurs more than one time in any constituent or in any formula depicting and describing compounds of the present invention, its definition on each occurrence is independent of its definition at every other occurrence. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

Unless expressly stated to the contrary, substitution by a named substituent is permitted on any atom in a ring provided such ring substitution is chemically allowed and the result is a stable compound.

As would be recognized by one of ordinary skill in the art, certain of the compounds of the present invention can exist as tautomers. All tautomeric forms of these compounds, whether isolated individually or in mixtures, are within the scope of the present invention. For example, in instances where a hydroxy (—OH) substituent is permitted on a heteroaromatic ring and keto-enol tautomerism is possible, it is understood that the substituent might in fact be present, in whole or in part, in the keto form, as exemplified here for a hydroxypyridinyl substituent:

Compounds of the present invention having a hydroxy substituent on a carbon atom of a heteroaromatic ring are understood to include compounds in which only the hydroxy is present, compounds in which only the tautomeric keto form (i.e., an oxo substituent) is present, and compounds in which the keto and enol forms are both present.

A “stable” compound is a compound which can be prepared and isolated and whose structure and properties remain or can be caused to remain essentially unchanged for a period of time sufficient to allow use of the compound for the purposes described herein (e.g., therapeutic or prophylactic administration to a subject). The compounds of the present invention are limited to stable compounds embraced by Formula I.

The term “halogen” (or “halo”) refers to fluorine, chlorine, bromine and iodine (alternatively referred to as fluoro, chloro, bromo, and iodo).

The term “haloalkyl” refers to an alkyl group as defined above in which one or more of the hydrogen atoms have been replaced with a halogen (i.e., F, Cl, Br and/or I). Thus, for example, “C₁₋₆ haloalkyl” (or “C₁-C₆ haloalkyl”) refers to a C₁ to C₆ linear or branched alkyl group as defined above with one or more halogen substituents. The term “fluoroalkyl” has an analogous meaning except that the halogen substituents are restricted to fluoro. Suitable fluoroalkyl groups include the series (CH₂)₀₋₄CF₃ (i.e., trifluoromethyl, 2,2,2-trifluoroethyl, 3,3,3-trifluoro-n-propyl, etc.). A fluoroalkyl of particular interest is CF₃.

The term “C(O)” refers to carbonyl. The terms “S(O)₂” and “SO₂” each refer to sulfonyl. The term “S(O)” refers to sulfinyl.

“Acyl” group refers to the C(O)—R″ group, where R″ is selected preferably from hydrogen, hydroxy, alkyl, haloalkyl, cycloalkyl, substituted amino, aryl optionally substituted with one or more alkyl, haloalkyl, alkoxy, halo and substituted amino groups, heteroaryl (bonded through a ring carbon) optionally substituted with one or more alkyl, haloalkyl, alkoxy, halo and substituted amino groups and heteroalicyclic (bonded through a ring carbon) optionally substituted with one or more alkyl, haloalkyl, alkoxy, halo and substituted amino groups. Acyl groups include aldehydes, ketones, acids, acid halides, esters and amides. Preferred acyl groups are carboxy groups, e.g., acids and esters.

Esters include amino acid ester derivatives. The acyl group may be attached to a compound's backbone at either end of the acyl group, i.e., via the C or the R″. Where the acyl group is attached via the R″, then C will bear another substituent, such as hydrogen or alkyl.

The term “sulfonyl” means a —SO₂—R group in which R is hydrogen, alkyl, a carbocycle, a heterocycle, carbocycle-substituted alkyl or heterocycle-substituted alkyl wherein the alkyl, alkoxy, carbocycle and heterocycle are as defined herein. Particular sulfonyl groups are alkylsulfonyl (i.e., —SO₂-alkyl), for example methylsulfonyl; arylsulfonyl, for example phenylsulfonyl; aralkylsulfonyl, for example benzylsulfonyl.

The term “sulfamoyl” means a —SO₂—NRR′ group in which R and R′ are independently hydrogen, alkyl, a carbocycle, a heterocycle, carbocycle-substituted alkyl or heterocycle-substituted alkyl wherein the alkyl, alkoxy, carbocycle and heterocycle are as defined herein. Particular sulfamoyl groups are alkylsulfamoyl (i.e., —SO₂—NH-alkyl and —SO₂—N-alkyl₂), for example methylsulfamoyl; arylsulfamoyl, for example phenylsulfamoyl; aralkylsulfamoyl, for example benzylsulfamoyl.

From all of the above, it is clear to the skilled person that any group whose name is a composite name such as, for instance, cycloalkylalkyl, arylalkyl, heterocyclylalkyl, alkoxy, alkylthio, aryloxy, arylalkyloxy, alkylcarbonyloxy, arylalkyl, heterocyclylalkyl and the like, have to be intended as conventionally construed by the parts from which they derive. As an example, a group such as heterocyclylalkyloxy is an alkoxy group, e.g. alkyloxy, wherein the alkyl moiety is further substituted by a heterocyclyl group, and wherein alkyl and heterocyclyl are as above defined.

The term “salt” means any ionic compound formed between one of the embodiments of the present invention and an acidic or basic molecule that can donate or accept ionic particle to/from its partner. Quaternary amine salts are also included. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the formula (I) may be formed, for example, by reacting a compound of formula (I) with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilisation.

The term “physiologically acceptable salt” refers to those salts that retain the biological effectiveness and properties of the particular compound. Physiologically acceptable salts are often useful because they may have improved stability and/or solubility in pharmaceutical compositions over the free base form or free acid form of the compound. A physiologically acceptable salt may be obtained by reaction of a free base with an inorganic acid such as hydrochloric acid, hydrobromic acid, nitric acid, phosphoric acid, sulfuric acid, and perchloric acid and the like, or with an organic acid such as acetic acid, oxalic acid, malic acid, maleic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, tartaric acid, citric acid, succinic acid or malonic acid, and the like. A physiologically acceptable salt may also be obtained by reaction of a free acid with a base such as sodium, potassium or lithium hydroxide, bicarbonate or carbonate, and the like.

Exemplary acid addition salts include acetates, adipates, alginates, ascorbates, aspartates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, cyclopentanepropionates, digluconates, dodecylsulfates, ethanesulfonates, fumarates, glucoheptanoates, glycerophosphates, hemisulfates, heptanoates, hexanoates, hydrochlorides, hydrobromides, hydroiodides, 2-hydroxyethanesulfonates, lactates, maleates, methanesulfonates, 2-naphthalenesulfonates, nicotinates, nitrates, oxalates, pectinates, persulfates, 3-phenylpropionates, phosphates, picrates, pivalates, propionates, salicylates, succinates, sulfates, sulfonates, tartarates, thiocyanates, toluenesulfonates (or tosylates) undecanoates, and the like. Additionally, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are known.

Physiologically acceptable salts of the compounds of formula (I) also include the salts with inorganic or organic bases, e.g., alkali or alkaline-earth metals, in particular sodium, potassium, lithium, calcium, magnesium, ammonium, iron, copper, zinc, manganese, aluminum salts and the like. Particularly base addition salts are the ammonium, potassium, sodium, calcium and magnesium salts. Salts derived from pharmaceutically acceptable organic non-toxic bases includes salts of primary, secondary, and tertiary amines, substituted amines (including naturally occurring substituted amines), cyclic amines and basic ion exchange resins, such as isopropylamine, diethylamine, trimethylamine, tripropylamine, triethylamine, ethanolamine, 2-diethylaminoethanol, trimethamine, dicyclohexylamine, lysine, arginine, histidine, procaine, hydrabamine, choline, betaine, ethylenediamine, glucosamine, methylglucamine, theobromine, purines, piperizine, piperidine, N-ethylpiperidine, polyamine resins and the like. Particularly organic non-toxic bases are isopropylamine, diethylamine, ethanolamine, trimethamine, dicyclohexylamine, choline, and caffeine.

The term “solvate” means a compound formed by the combination of solvent molecules with molecules or ions of the solute (solvation). Solute can be any of the embodiments of the present invention and the solvent can be water or any organic solvent.

As noted above, the present invention provides 4,6 disubstituted aminopyrimidines, physiologically acceptable salts thereof and uses thereof. The compounds are generally of the formula:

It may be advantageous for certain uses to enhance the solubility and/or bioavailability of one or more of the compounds of the present invention.

Unless otherwise specified, when referring to the compounds of formula (I) per se as well as to any pharmaceutical composition thereof or to any therapeutic treatment comprising them, the present invention includes all of the isomers, tautomers, hydrates, solvates, complexes, metabolites, pro-drugs, carriers, N-oxides and pharmaceutically acceptable salts of the compounds of this invention.

A metabolite of a compound of formula (I) is any compound into which this same compound of formula (I) is converted in vivo, for instance upon administration to a mammal in need thereof. Typically, without however representing a limiting example, upon administration of a compounds of formula (I), this same derivative may be converted into a variety of compounds, for instance including more soluble derivatives like hydroxylated derivatives, which are easily excreted. Hence, depending upon the metabolic pathway thus occurring, any of these hydroxylated derivatives may be regarded as a metabolite of the compounds of formula (I).

It may be advantageous for certain uses to prepare a compound (or physiologically acceptable salt thereof) as a “prodrug.” As used herein, the term “compound” encompasses a prodrug form of the parent compound. “Prodrug” herein refers to a chemical substance, preferably but not only covalently bonded, that is converted into the parent compound (I) in vivo. Prodrugs often are useful because, in some situations, they may be easier to administer than the parent compound. They may, for instance, be bioavailable by oral administration whereas the parent compound is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent compound. An example of a prodrug would be a parent compound of the present invention which is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility. The ester is then metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water solubility is beneficial. Such a prodrug is generally inactive (or less active) until converted to the active form.

N-oxides are compounds of formula (I) wherein nitrogen and oxigen are tethered through a dative bond.

If a chiral center or another form of an isomeric center is present in a compound of the present invention, all forms of such isomer or isomers, including enantiomers and diastereomers, are intended to be covered herein. Compounds containing a chiral center may be used as a racemic mixture, an enantiomerically enriched mixture, or the racemic mixture may be separated using well-known techniques and an individual enantiomer may be used alone. In cases in which compounds have unsaturated carbon-carbon double bonds, both the cis (Z) and trans (E) isomers are within the scope of this invention. In cases wherein compounds may exist in tautomeric forms, such as keto-enol tautomers, each tautomeric form is contemplated as being included within this invention whether existing in equilibrium or predominantly in one form.

Pharmaceutical compositions of the compounds and the physiologically acceptable salts thereof are preferred embodiments of this invention. Pharmaceutical compositions of the compounds of the present invention (i.e., compounds and salts thereof as described above) may be manufactured by processes well known in the art; e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.

Pharmaceutical compositions may be formulated in a conventional manner using one or more physiologically acceptable carriers or diluents. Proper formulation is generally dependent upon the route of administration chosen.

Methods and Results In Vitro CDK9/CyclinT Assay

The activity of the compounds described in the present invention can be determined by measuring the phosphorylation of a fluorescently-labeled peptide by human CDK9/CyclinT kinase complex by fluorescent polarization using a commercially available IMAP Screening Express Assay Kit (Molecular devices).

Test compounds were diluted in 100% DMSO to 5 mM stock concentration, then further dilutions were made in H₂O or 100% DMSO to desirable concentrations. Each reaction consisted of 5 nM enzyme: CDK9/CyclinT (Proqinase cat#0371-0345-1), 400 nM TAMRA-Rbtide (synthetic 15-mer peptide derived from human retinoblastoma tumor suppressor protein labeled with TAMRA dye, Genecust Europe), 12 μM ATP (=Km_(app), Sigma-Aldrich) and kinase buffer: 20 mM MOPS pH 7 (Sigma-Aldrich), 1 mM DTT (Sigma-Aldrich), 10 mM MgCl₂ (Sigma-Aldrich), 0.01% Tween 20 (Sigma-Aldrich).

For each reaction, 4 or 6 μl containing TAMRA-Rbtide, ATP and kianse buffer were combined with 2 μl diluted compound in H₂O or 0.028 μl compound in 100% DMSO. The kinase reaction was started by the addition of 2 μl diluted enzyme. The reaction was allowed to run for 1 hour at room temperature. The reaction was stopped by adding 15 μl IMAP beads (1:400 beads in progressive (100% buffer A) 1× buffer). After an additional 1 hour, fluorescent polarization (Ex: 550-10 nm, Em: 590-10 nm, Dich: 561 nm) was measured using an Analyst GT (Molecular devices).

Biological Assays

The biological activity of the compounds described in the present invention was evaluated in the following assays:

Antiviral Activity Against HIV (AV)

Activated primary T cells are infected with a laboratory strain of HIV-1, then cultured and exposed to different concentrations of the test compounds. HIV replication is analysed by measuring the viral protein p24 and expressed as percentage of untreated control. Inhibition of viral replication (AV) is then calculated (AV=100 minus the % p24 compared to control, AV of control=0%). Inhibitory concentration 50% for antiviral activity (AV₅₀) is calculated.

Antiproliferative Activity (AP)

Primary T cells are cultured and exposed to different concentrations of the test compounds. Cell proliferation is analysed by measuring mitotic index (ie the number of cell divisions a population of cells undergoes) through flow cytometry based techniques. Mitotic index is expressed as percentage of untreated control. Inhibition of cell proliferation (AP) is then calculated (AP=100 minus % mitotic index compared to control, AP of control=0%). Inhibitory concentration 50% for antiproliferative capacity (AP₅₀) is calculated.

Cytotoxicity

Primary T cells are cultured and treated with different concentrations of the test compound. Viability is analysed by measuring through flow cytometry based techniques the percentage of viable cells, compared to untreated control=100%). Toxic dose 50% (TD₅₀) is calculated.

In all the biological assays, commercially available CDK9 inhibitors were also included in the analysis: Flavopiridol (Alvocidib, Sanofi-Aventis) and Roscovitine (Seliciclib, Cyclacel). In Tables 2, 3 and 4, ND means Not Determined.

We identified several compounds with good antiviral and antiproliferative activity and a good cytotoxicity profile: examples 5, 10, 13, 16, 26, 31, 32, 41, 43, 45, 62, 64, 73, 75, 79, 83, 111, 112, 123, 127, 128, 129, 130, 131, 141, 142, 143, 144, 145, 146, 147. The analysis of the commercially available compounds showed that there is no correlation between CDK9 inhibition and anti-HIV activity. In fact despite having a potent CDK9 IC₅₀ value Roscovitine and Flavopiridol demonstrated a poor anti-HIV and cytotoxicity profile in our assay.

When we tested compounds with potent anti-CDK9 activity (already published in the patent application WO2011077171 A1) we compared these test results to those of the commercially available compounds Roscovitine and Flavopiridol. Unexpectedly we didn't find a direct correlation between CDK9 inhibition and good antiviral activity. The following table shows some examples of compounds with potent CDK9 IC₅₀ values though not having a good antiviral activity profile.
